The other day I wrote about how I compiled and installed support for git on Mac OS X 10.5. I also use a laptop with Mac OS X 10.4 and thought naïvely that the same would work on Tiger. I was sorely mistaken.
Apparently git has a few dependencies which must have been met on Leopard but caused errors on Tiger. The dependencies are to the packages expat and asciidoc. To compile support for those the following can be done prior to running the installation of git.
# Install expat
tar -xvzf expat-2.0.1.tar.gz
sudo make install
# Install asciidoc
tar -xvzf asciidoc-8.2.7.tar.gz2
Once this is done, the installation of git should go smoothly.
